高分子材料可以应用到国际热核实验反应堆(ITER)中国实验包层(TBM)涉氚系统的非初级包容系统作为阻氚迁移扩散的材料之一。以几种高分子材料胶乳为原料采用涂布工艺制备了一定厚度的高分子片材,使用氢气作为介质通过渗透实验获得了氢气在几种材料中的渗透率,这些数据可作为氚防护手套和氚防护服的材料选择依据之一。以丁基胶乳为例进一步研究了胶乳的成膜性能和吸水性能,结果表明烘干脱水温度和硫化温度对成膜质量有重要影响,缓慢的升温烘干脱水和低温快速硫化可以获得较少内部缺陷的橡胶材料。由于胶乳中含有亲水物质而导致成型后橡胶材料的吸水性增强,而沥滤处理可以减少橡胶内的亲水物质从而降低材料的吸水性。
Polymeric materials can be applied to the non-primary containment system of the ITER China Experimental Cladding (TBM) Tritium-Containing System as one of the materials that resist the migration of tritium. Several kinds of polymeric latexes were used as raw materials to prepare polymer sheets with a certain thickness through the coating process. Hydrogen was used as the medium to obtain the permeability of hydrogen in several materials by using the permeation experiments. These data can be used as tritium protective gloves and Tritium protective clothing material selection based on one. The butyl latex was used as an example to further study the film-forming properties and water absorption properties of the latex. The results show that the drying and dehydration temperature and the vulcanization temperature have an important influence on the film quality. Slowly drying, dehydration and low temperature rapid vulcanization can obtain less internal Defective rubber material. Due to the presence of hydrophilic material in the latex, the water absorption of the rubber material after molding is enhanced, and the leaching treatment can reduce the hydrophilic material in the rubber to reduce the water absorption of the material.
